Bigger is best with goldies. Some of the ornamentlas canbe done ok in
a decent sized tank, but make sure yu have a larger than normal filter
as they are messy compared to the tropical type fish......Defnately no
koi, unless in a month or two yu have apoace to put them. They
certainly are ot suited for aquarium confinement. Heck get 2 common
10 cent feeder comets, and when they outgrow it flush em and start
again.......thats what most folks do, but really, comets do best in a
large tank or outside and not over crowded, and cooler waters....
The small marble sized black moors or such do fair in a decent sized
tank, and personally I would go with a 29 gal minimum and they can be
hgad relatively cheap ready to go with filter etc, and once you decide
yu canalways upgrade the filter if its insufficient. As to what
filter, its all a personal choice but bigger is better just ilke with
the tank.....A small pair of moors(Marble sized or so) can easily
get 3 to 5 years of use out of a 29 gal tank until they get too the
pint of needing more room.

Have fun

Hi, I'm thinking about trying a tank with gold fish in it for the first
time. I dont want to buy some gigantic aquarium or anything, I was thinking
about trying to find something acrylic in the 10 to 20 gallon range. Would
this be a good enviroment for goldfish? How about fancy goldfish or koi?
What kind filtration system should I be looking at? I've heard that goldfish
produce a lot of waste so I want to make sure I get a good filter in place.
Is an undergravel filter adequate? How about one of those biowheel under the
hood things? What kind of fish gravel should I be looking at? Should I get a
sucker fish to put in there with them? I want to make sure I get a setup
that can meet the needs of the fish and that they wont outgrow. Any
information would be great thanks.
